Very helpful, thank you. Phase is the argument or angle of the complex number

I am sorry but I don't understand why use a complex number ? Like if I have to explain this to a bunch of 15 year olds ?

Hi, could you tell my how if I want to square root a negative number, instead of it showing a math error, it returns a complex number? for example square root of -2.25 says it cannot be done, but it can be represented as 1.5i, but python doesn't get that
